Selective permissiveness of TPA differentiated THP-1 myelomonocytic cells for human cytomegalovirus strains AD169 and Towne

Microb Pathog. 1994 May;16(5):373-8. doi: 10.1006/mpat.1994.1037.


Two highly passaged laboratory strains of human cytomegalovirus (HCMV), AD169 and Towne, were tested for their ability to infect and replicate in THP-1 myelomonocytic cells differentiated with 12-O-tetradecanoylphorbol-13-acetate (TPA). TPA treatment of human THP-1 cells increased the number of cells that expressed HCMV immediate early (IE1) antigen from 0.06% prior to TPA treatment to 12% following cell differentiation. The Towne but not the AD169 strain replicated in differentiated THP-1 cells as determined by HCMV DNA replication and infectious virus production. Major early (HCMVTRL4) mRNA was present in both the abortive and productive THP-1 cell infections.
